D800 Firmware Update Focus Improvement!

After reading this I decided to take a look at my micro-adjustment and couldn't believe my eyes. I had carefully adjusted all my lenses a few weeks ago and then did the firmware update. My 50mm 1.8g was adjusted to -2 saved and after the firmware update it was -1 default, +2 saved. My 14-24 originally was at +2 now it is at -1+10. Sharpness at all zoom focal links seems to be better. For some reason Nikon has decided to use default and saved settings for micro-adjustment, does anyone understand why this is? Why not just use the saved number? I'm on my way back to the studio start testing my other lenses.
